Ops-minded engineer, developer at heart

Portrait of Efe Özgen

efe@ozgen

I'm a DevOps Engineer at Practicus AI, where I administer production Kubernetes and OpenShift clusters, build the alerting that keeps them dependable, and manage the platform tooling with Helm.

My path started with internships at Summarify, Soliner and Jotform, then a full-time role at Odeal — GitOps with ArgoCD, CI/CD with GitLab CI and Jenkins, monitoring with Prometheus and Grafana, even building a Linux OS from scratch. That mix of infrastructure depth and developer empathy is what I bring to every platform I operate.

Computer Science & Engineering graduate from Marmara University. Outside of clusters, I co-build RunKoc — a full-stack sports club platform — and write about engineering on Medium.
